BB-B Series Hydraulic Gear Oil Pumps Materials BB-B4

The internal structure of BB-B primarily involves a hydraulic system, with its core being the precise engagement of the internal gear (outer rotor) and the external gear (inner rotor). The internal gear features an arc-shaped tooth profile, while the external gear adopts a curtate cycloid design. The two components achieve low noise, high-speed operation, and excellent self-priming performance through an internal meshing design. This configuration is suitable for hydraulic systems with operating pressures below 25MPa, ensuring smooth and efficient oil delivery.
